The reverse was also used: testing for the presence of thiocyanate by the addition of ferric salts. The 1:1 complex of thiocyanate and iron is deeply red. The effect was first reported in 1826. [15] The structure of this species has never been confirmed by X-ray crystallography. The test is largely archaic.
Thiocyanate [6] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. [7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.
Clar's rule states that for a benzenoid polycyclic aromatic hydrocarbon (i.e. one with only hexagonal rings), the resonance structure with the largest number of disjoint aromatic π-sextets is the most important to characterize its chemical and physical properties. Such a resonance structure is called a Clar structure. In other words, a ...
Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.
President-elect Donald Trump had not been terribly successful in suing media organizations until this weekend when ABC News agreed to settle a closely-watched defamation case he brought against ...
The Hg(SCN) 3− ion can also exist independently and is easily generated from the compounds above, amongst others. [5] Organic halides attack Hg(SCN) 2 to give a mercuric halide and a mixture of the corresponding thiocyanate and isothiocyanate. [6] Mercuric thiocyanate catalyzes HSCN or BrSCN addition (either reagent formed in situ) to alkynes ...
